Boeing booked the order from GE Capital Aviation Services, the commercial aircraft leasing and financing arm of General Electric Co., in 2013. It had been listed as an unidentified buyer on Chicago-based Boeing's website.

The order consists of 40 737s. Half are 737 Max, and 8s half are next-generation 737-800s.

With the new order, the GE aircraft arm has ordered 638 airplanes directly from Boeing.
